GAS-METER ATTACHMENT.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed June as, 1916. Serial in. 106,314.

a To all whom. it may concern:

Be it known that I, HENRY C. Monnrs, a citizen of the United States, and a resident of the city of Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Gas-Meter Attachments, of which the following is a specification, reference being made to the accompanying drawings, forming a part thereof.

My invention relates to attachments for gas or other fluid meters designed to operate with sliding valves which open and close ports to permit gas or other fluid to go in and out of diaphragm chambers, which in turn operatethe registering mechanism for the measurement of gas that may pass through the meter. j

In meters of that type wherein the measurement of gas is accomplished by means of sliding valves and diaphragms, operating registering mechanism of the meter, the valve covers operate unrestrictedly upon their seats, being normally held in place by their weight or by gravity. Therefore, while the meter is maintained in an upright position, the valve covers will remain properly seated and operate the mechanism for meas-' uring flow of gas through the meter.

If, however, in this or similar types of meter, the meter be dislodged or moved from its normal upright position, the valve covers will be unseated and gas will pass through the meter without actuating the valves and without causing a registration of the flow of gas through the meter.

The objects of my invention, among other things, are to provide a pimple and effective automatically-actuated device in conjunc-' tion with a valve located within the valve case and coacting with the short inlet pipe of a meter, whereby such valve, which is normally held open when the meter is -maintained in its usual upright position, will be immediately closed to shut off the inflow of gas to the valve case whenever the meter is accidentally or purposely tipped or tilted In the embodiment illustrated, I have arranged a weight of suitable shape andsize which shall shift or tilt when the meter is moved from its upright position, the weight, by its movement, actuating a crank arm suitably disposed to automatically close the valve on its seat formed on the orifice of the inlet pipe to the valve casing, whenever such weight shall be shifted or tilted, and to open the valve when the meter is restored to its normal position.

Other objects and advantages of my improved attachment will be hereinafter set forth and particularly pointed out in the appended claims.

In the accompanying drawings, Figure l is a top plan view of a meter provided with the shut-0E valve, the cover of the valve case being removed;

' Fig. 2 is a fragmentary sectional view of the upper portion of a meter, the section being taken onthe line 2-2 shown in Fig. 1, the cover of the valve case being shown in position;

Fig. 3 is an enlarged sectional view illustrating the shut-off valve in normal position; and a Fig. i is aview similar to Fig. 3, illustrating the meter'tipped and the shut-off valve closed.

Similar numerals refer to similar parts throughout the several figures.

In the drawings, 5 indicates the, gas meter having the register 6 secured tov one side thereof, with the inlet pipe 7 and the outlet pipe 8 oppositely disposed to each other, as shown in Fig. 1. The mechanism for operating the register 6 isof well-known construction and arrangement within the valve case 9, and comprises the valve covers 10' sliding on the valve seats 11, which covers 10 carry rods 12 connected in turn b links 13 to a vertically-disposed shaft 14: which is rotated by the diaphragms in the meter (not shown), and links, to rotate the gear wheel 15 mounted on the shaft 16 connected with the registering devices mechanism constitutes, in itself, no part of my invention, and is old and well-known, its construction and operation need not be described.

through suitable arms in the register 6. As this The inlet pipe 7 has the short inflow pipe I 17 connected at right angles therewith, the

inner end of which,

projecting into the valve case 9, forms the valve seat 18 preferably just above the floor 19 of the valve case 9, as shown in Fig. 2. On the floor 19 of the valve case 9 is the weight 20, loosely supported thereon and normally resting in an upright position within the valve case, as shown in Fig. 3. Arranged on two sides of the weight 20, are two bearing blocks 21 and 22, each secured to the floor 19 subin Fig. 3 and thence stantially in the positions shown in Fig. 1. The weight 20 carries the crank arm 23,

journaled in the lower portion of the weight,

preferably midway between its lower bearing edges 24. The end 25 of the arm 23 extends at substantially right angles from the side edge 24 of the weight 20, and is then bent to pass through the bearing block 22 and terminates in the right angled free arm 26., which is adapted to be lifted from, and lowered to, the floor 19 as the position of the weight 20 is changed from the tipping of the meter, the. arm 26 being uplifted when the weight 20 is in its vertical position, as shown in Fig. 2.. The other end 27 of the crank arm 23 is bent to extend diagonally upward from the weight 20, as shown passes through the bearing block 21, whose bearing is slightly higher from the floor 19 than the bearing of the arm 23 within the weight 20, as is clearly shown in Fig. 3, when the weight 20 is in its normal upright position. After passing through the block 21, the end 27 is bent at substantially rightanglesv and carries on its outer end 28 the valve 29 adapted, when lowered, to engage the valve seat 18 on the inflow pipe 17 the valve being held uplifted when the meter and weight 20 are held in vertical position.

Whenever the weight 20 is tipped or tilted through the abnormal movement of the meter from its vertical position, such tilting movement raises the axis of the crank arm 23! within the weight 20 to the level of the axis: of the bearing within the block 21, thereby forcing the valve 29 down on its seat 18, as is clearly shown in Fig. 4:, from its normal uplifted position shown in Fig. 3,. when the weight 20 rests horizontally on the floor 19, the meter being maintained in its normal upright position. On the other hand, when the weight 20 is tilted, as shown in Fig. 4, so as to close the valve 29 to shut off the inflow of gas from the pipe 17 to the valve case 9, its further movement from the perpendicular is prevented by the arm 26. being lowered from its normal uplifted position to. rest, on the floor 19, thereby limiting the tilting of the weight 20 after the valve 2.9 has been closed.

It. will be apparent that my attachment serves to immediately and effectively shut off the inflow of gas to the valve case of the meter, whereby the register and its operating mechanism are caused to stop operating, whenever the meter is tipped or tilted from its. normal upright position, either from accident or design; and that, further, I have provided a simple device to limit the tilting movement of the weight after the latter has performed its function in lowering the valve upon its seat on the inflow pipe.

It will be understood that the mechanism shown may be variously modified and changed without departing from the limits and advantages of my invention, provided the operation is substantially as indicated; and it will also be understood that the invention is not limited to any particular form or construction of the parts except in so far as such limitations are specified in the claims.
